The PAA2 is VERY handy for setting frequency balances. I recently bought a pair of Eminent Technology LFT-8s. As my much-loved main amps are ASL 805 SETs with only 50 Watts of power, I quickly biamped them using an old Dalquist DQLP1 electronic crossover and 2 channels of my Outlaw 770. One thing about a crossover with bass level, crossover points, and bottom-octave boost controls--it's REALLY easy to bollox things up. Using the PAA2 eased the task dramatically.
It was highly useful for setting MR high-pass filtering and tweeter low-pass filtering, too.
However, I still find an analog meter easier for setting overall levels. I've had a Hall Engineering calibrated generator and meter system for maybe 30 years now; its meter is based on the analog RadShack meter but uses a long snout to get the microfone farther from the person using it, and it has a 'flat' setting. It's really easy to read levels to a quarter dB, whereas the digital readout, even with its multiple time-weighted options, is bouncing about so much it's more difficult to use.
So the PAA2 is highly useful for frequency-based measurements, and I'm very glad I have one.
